of the Wheel; and Fig. 2, a section of part thereof, showing the form and local relation of the chutes and buckets.

A indicates acylindrical case or waterreservoir supported by a suitable frame; B, the flume or conduit thereof 5 and O, a gate for controlling the flow of water to the wheel. The part D is formed of a ring provided with a series of openings, and with straight chutes E, which are set at an inclination of about forty-five degrees to the axis of the sha-itl?, and beveledon one side'of their upper edges,- as shown in Fig. 2. This part D is firmly secured to or formed in one piece with the case A. On the shaft F is keyed the wheel proper E, and the shaft is stepped in the frame in a suitable manner so that they revolve together. The wheelE is provided with buckets G, which are mainly perpendicular in their upper part a to a plane which is parallel to the chutes E', and from thence they curve gradually down ward to a horizontal plane. Against the part `c the water delivered by the chutes strikes with a direct impulse, and thus imparts a maximum of force to the wheel E, causing it to revolve rapidly. The curved or extended lower portion of the buckets tends to increase the reactive impulse of the water,while the latter finds ready escape or exit in consequence of the periphery of the Wheel E being flared or beveled outward from its upper to its lower edgel Thus the water accumulating in the reservoir A descends in a straight course directly against the part of the buckets perpendicular to the chutes, and is caused to give a further reactive impulse by reason of the construction of the lower part of the buckets, from which it finds ready escape.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The improved wheel formed by the straight inclined chute plates E and buckets G a, curved as shown and described, and secured in a ring beveled or dared outward at its lower edge, all arranged and operating as set forth. y
